Elephant 0.9.1 is now officially released.
Instructions for downloading it via darcs can be found here:
http://common-lisp.net/project/elephant/downloads.html
The release provides official support for using Postmodern http://common-lisp.net/project/postmodern/ as a back-end data repository on top of Postgres. This back-end is about three times faster than the generic SQL interface on top of Postgres. There are some other improvements as well.
Note that existing Postgres repositories are not compatible with a Postmodern repository. However, Elephant provides powerful multi-repository migration. If you have an existing Postgres repository and want to migrate to Postmodern, you should create a completely new Postmodern repository and migrate all of your data into it. The migration can be accomplished with a single command.
If you have been using the (unofficially released) postmodern backend, you will have to migrate your data into a CL-SQL based postgres backend, or into a BDB backend, and then migrate into your new postmodern repository. This release is not compatible with previous (development) versions of the postmodern functionality.
Thanks very much to Henrik Hejte and the postmodern team for this functionality, and to Ian Eslick for other improvements.
This release has been tested on a 64-bit Linux with SBCL 1.0.10, and other platforms as well. If anybody downloads it and tests it, please run the (large) set of automated tests and report your results to elphant-devel at common-lisp.net. I will update the platforms page:
http://common-lisp.net/project/elephant/platforms.html
as I receive your updates.
Henrik has creates some new documentation which can be build from the source, but I have been unable to build it, so have not updated the website.
